According to the invention, a search is carried out across the subnetworks by a respective selected client (CSA, CSB, CSC) for other selected clients and for the server (SRV), whereby when it locates the server (SRV), the selected client stores server address information (SA) identifying said server and when it locates another selected client, it requests the server address information (SA) from that client and stores it on receipt. The stored server address information (SA) is transmitted by the selected client (CSA, CSB, CSC) to one or a plurality of other selected or non-selected clients (CSA, CSB, CSC, C1, C2, C3, CL).
Description
Technical field
Popular communication-or data handling system often is distributed in a plurality of subnets, for example on the so-called local network (LAN), described local network is being connected to each other to bigger network, for example is being connected on the wide area network (WAN) aspect it.The communication of this distribution-or an important structural principle of data handling system be so-called client-server-principle.Be called an equipment in this case as server, this equipment in a distributed system for being distributed in a plurality of service-users, so-called client computer in the network, centralized traffic being provided.The common utonomous working of client-server, in other words, the client computer that server does not rely on separately provides its business.A client computer can only require such business, and this business is provided by a governable server, and wherein this client computer no longer includes influence to the execution by this server after using a kind of business.
Background technology
For use by client computer the business that provides by a server essential be that described server can be discerned and the described client computer of addressing or described client's function are discerned and the described server of addressing.In other words, belong to described server as the related client computer in interactional basis between client computer and the server.
In many cases, especially in the network based on Internet Protocol, a server-assignment is undertaken by manual configuration related client computer or server to client computer.Usually in this case in server the Internet Protocol address of each client computer of configuration or in client computer the Internet Protocol address of configuration server.Client-server is distributed inferentially mutually by this way.A kind of such manual configuration especially requires sizable cost in the macroreticular of the potential customers' machine with high quantity.Draw in addition, divide timing, for example by being transferred on the new server or the manual configuration of the essential a kind of renewal of the interpolation of New Client each the change.
Automatic distribution method, so-called automatic discovering method are adopted in height cost based on a kind of manual configuration more and more.A kind of method of frequent application based on, (DHCP: DHCP), this Dynamic Host Configuration Protocol server can use client computer-or server address in inquiry to dispose so-called Dynamic Host Configuration Protocol server like this.A kind of such method is as prerequisite, and the Dynamic Host Configuration Protocol server of corresponding configuration is governable in each subnet and crosses over subnet ground and arrange.Change client-server-minute timing and must correspondingly upgrade configuration data in the DHCPp server each in this case.For example from the known Dynamic Host Configuration Protocol server of the Internet documents imported March by R.Droms1997 " Request for Comments:2131, Dynamic Host ConfigurationProtocol (Request for Comment: 2131, DHCP) ".
Summary of the invention
Task of the present invention is, provides a kind of being used for to distribute to the method for a server with being distributed in client computer on a plurality of subnets, and this method requires configuration cost still less.Task of the present invention in addition is, a client computer that is used to carry out described method is provided.
The client computer of the method for the feature of described task by having claim 1 and the feature by having claim 7 solves.
At method of the present invention place, distribute to a server and in subnet separately, select one of client computer in order to be distributed in client computer on a plurality of subnets such as the local network.Cross over subnet ground according to the present invention by a selected separately client computer and seek other selected client computer and seek described server, wherein selected client computer is stored the server address information of this server of identification and is inquired server address information and stored this server address information when receiving by this client computer when finding another selected client computer when finding server.The server address information of being stored is transmitted to one or more other client computer selected or that do not select from selected client computer.
Can carry out the server of a plurality of selected client computer of seeking different sub-network side by side by the inventive method.Usually can find one of selected client computer soon based on described searching server arranged side by side.Server to be sought needn't be modified in order to carry out described method.Selected separately client's function is the inquiry identified server of the Service-Port by belonging to a kind of business to be used for example.As long as this server is found by one of selected client computer, server address information just can, from selected client computer, also therefore distribute to client computer by other client computer tandem type selected or that do not select ground, this client computer belongs to the server that is found by this way with crossing over subnet soon.
The present invention allows client-server-distribution a kind of dispersion and that oneself organize in fact.Especially the unnecessary concentrated information service such as the configuration again of DHCP or a kind of manual configuration or client computer, server or other network componentses.
Another advantage of the present invention is, carries out the effective server of seeking and can be restricted to selected client computer, and this produces than little a lot of offered load when All Clients is sought server.
The inventive method is with wait little when new coupling client computer or a new server-or setup time and outstanding more in addition, because this method for the client computer of new coupling in order to receive that server address information is enough, replace server itself, find a selected client computer, this client computer has obtained server address information.If the selected client computer of the subnet of oneself has obtained server address information, a client computer that newly is coupling on the described subnet provides server address information in simple especially mode so.
Advantageous embodiment of the present invention and expansion scheme provide in the dependent claims.
The server address information of being stored especially can cause by an inquiry from described client computer to the transmission of at least one other client computer selected or that do not select.Preferably server address information from selected client computer respectively oneself primitively (eigeninitiativ) or since inquiry send its own subnet to all belong to the client computer of this server and/or the selected client computer of all known these servers beyond its subnet.Server address information allows the distribution of the tandem type of very fast leap subnet ground server address information to the transmission of other client computer as much as possible.
Preferably selected client computer is stored the client address information of a described client computer of identification when finding another selected client computer.If such client address information can be pass on to the other client computer that has this situation to inquire.The described information of selected client computer of distributing to of the leap subnet by client address information can be formulated the topological diagram of its subnet environment and use at the communication of crossing over subnet.Selected in addition client's function is because the acquisition of described server address information sends this information to the one or more selected client computer of discerning by one or more client address information of storing.

Hereinafter explain embodiments of the invention in detail, illustrate in the diagram respectively at this by accompanying drawing:
One of Fig. 1 according to client computer of the present invention and
The network that comprise a plurality of subnets of Fig. 2-5 distinct methods in the stage
Embodiment
The network that comprises a plurality of subnet SNA, SNB, SNC and SND has schematically been described respectively in Fig. 2-5.At the embodiment hypothesis that exists, subnet SNA ..., SND is by based on the local network of Internet Protocol, so-called LAN (LAN: realize that local area network (LAN)) described local network intercouples by a wide area network (not shown) such as the internet.Subnet SND has a server S RV in this case, this server by Service-Port predetermined or dynamic assignment in network, arrange a kind of business, such as a kind of communication-, data processing-and/or information service.Subnet SNA comprises client computer C1, C2, C3 and CSA respectively in addition, and subnet SNB comprises client computer CL and CSB, and subnet SNC comprises client computer CL and CSC.Client computer CSA, CSB, CSC, C1, C2, C3 and CL must and belong to described server S RV by server S RV prepare to provide professional in this meaning.For with client computer CSA ..., CL distribute to server S RV necessity be, client computer CSA ..., the address information SA of an identified server SRV of CL identification, in the embodiment that exists, be the Internet Protocol address of a described server S RV.Be called mostly below the IP address server S RV Internet Protocol address SA by the inventive method send to client computer CSA ..., CL.
In Fig. 1, schematically described client computer CSB according to foundation of the present invention.Client computer CSB goes up network interface NS of domination in order to be coupled to subnet CSB.Client computer CSB has one and selects module CSEL to be used for from predetermined being connected identical subnet, selecting a client computer for SNB, client computer CL and CSB as client computer CSB herein of all or a group in addition.Described selection is finished by known so-called system of selection by all actings in conjunction of participating in the selection module CSEL of the client computer CSB of selection and CL.For example from Gupta, van Renesse of freely obtaining down for " http://www.cs.cornell.edu/home/rvr/papers/ProbLeaderElection.pd f " in the address by the internet on August 7th, 2003 and Birman the known a kind of such system of selection of document " A Probalbilistically correct Leader ElectionProtocol for Large Groups " in April, 2000 input.
At the embodiment hypothesis that exists, by selecting client computer CSB among the subnet SNB by client computer CSB and being chosen in of CL execution together.To this hypothesis, in subnet SNA, select client computer CSA and in subnet SNC, select client computer CSC similarly by client computer CL and CSC by client computer C1, C2, C3 and CSA.Therefore each in subnet SNA, SNB and SNC is accurately selected client computer CSA, a CSB or CSC.Correspondingly following client computer CSA, CSB and CSC are called selected client computer and client computer C1, C2, C3 and CL are called the client computer of not selecting.Selected separately client computer CSA, a CSB or CSC after it is selected (indicated as the double-head arrow that connects by a dotted line in Fig. 2) belong to the client computer of not selecting of its subnet SNA, SNB or SNC.Selected separately client computer CSA, a CSB or CSC can preferably send information to other parts by a so-called broadcasting report after it is selected, such as the client computer of not selecting of its subnet SNA, SNB or SNC.
In addition one of the client computer CSB shown in Fig. 1 domination seek module SM be used for crossing over subnet ground seek server S RV and other subnets, herein for the selected client computer of SNA and SNC, searching, be CSA and CSC herein.If find server S RV in addition, or IP address SA transmits by a client computer of selecting that is found, and client computer CSB has a memory MEM so, with the IP address SA of storage server SRV.Client computer CSB comprises an output module OUT in addition, the client computer CL that does not select that sends selected client computer CSA, the CSC of other subnets SNA, SNC to and send the subnet SNB of oneself to the server ip address SA that may store.Client computer CSA has identical with the client computer CSB shown in Fig. 1 in fact structure with CSC.
Fig. 3 illustrates the searching of the leap subnet of being carried out by selected client computer CSA, CSB and CSC after its selection separately.In the embodiment that exists, cause the transmission of the transmission of one first inquiry report QMB1 in subnet SNA and one second inquiry report QMB2 in subnet SND in the scope of searching module SM of client computer CSB in its searching.Do not rely on this selected client computer CSA and in subnet SNC, transmit an inquiry report QMA1.Inquiry report QMA1, QMB1 and QMB2 can prepare to provide its business by this Service-Port server S RV preferably at the port numbers of above mentioned Service-Port.Selected side by side therewith client computer CSA, CSB and CSC itself monitor described port numbers, suitably to operate the similar inquiry of other client computer.
A selected client computer, such as CSB can run into different client type beyond the subnet of oneself when it is sought.On the example of seeking client computer CSB by the transmission of inquiry report QMB1 and QMB2, depend on below sought, in other words separately inquiry report QMB1 or the type of the client computer that receives of QMB2 the additive method mode is described:
1. if find a unsupported client computer (not shown in FIG.) of the inventive method, the client computer CSB of Xun Zhaoing recognizes this and also continues its searching in the reaction that lacks an expectation so.
If 2. find one do not select but client computer such as C3 that the inventive method is supported, this client computer is not answered the client computer CSB of the searching among the embodiment of existence so, but tells the client computer CSA that selects with described inquiry in the subnet SNA of oneself.So the client computer CSA that is notified accepts described answer.This situation goes on to say by Fig. 4.The client computer CSB selected according to Fig. 4 will send the client computer C3 that does not select of subnet SNA at the inquiry report QMB1 of above mentioned port numbers to.Therefore client computer C3 is apprised of the inquiry of client computer CSB with the selected client computer CSA that report information IM sends its subnet SNA to by this subnet SNA client computer CSA.So client computer CSA sends client computer CSB answer inquiry to by answering report AM.If based on the inquiry identified server IP address SA of oneself, this client computer CSA utilizes server ip address SA to answer and reports that AM sends client computer CSB to client computer CSA.If opposite client computer CSA nonrecognition server ip address, this is notified to client computer CSB by a corresponding negative answer report so.Continue its searching at a negative client computer CSB who seeks the reporting agency that answers.
3. if find another selected client computer such as CSA or CSC, this client computer is directly answered the inquiry of client computer CSB so.If the client computer CSA that selects or the CSC that are found, based on the inquiry identified server IP address SA of oneself, this address is transferred to the client computer CSB that is inquired so.If client computer CSA that is found or CSC also do not have identified server IP address SA, so correspondingly transmit negative an answer and report.Continue its searching at a negative client computer CSB who seeks in the report place that answers.
Other information of exchange between the client computer of seeking and find of selecting preferably is with a width of cloth topological diagram of the network environment of formulating for example selected client computer.Advantageously the client computer CSB of Xun Zhaoing is stored in the IP address of all client computer that select and/or that do not select that find in its memory MEM.
4. if selected client computer CSB oneself finds server S RV, this client computer CSB discerns this according to server S RV to the reaction of its port inquiry and therefore the IP address SA of the server S RV that finds is stored in the memory MEM so.
Find server S RV in Fig. 3, to be illustrated.Inquiry report QMB2 is transmitted to the server S RV among the subnet SND in Fig. 3, answers report SAM so server S RV sends back one, recognizes server S RV according to the client computer CSB that inquires.Be stored in its memory MEM as server ip address recognizing the IP address of client computer CSB after the server S RV the server S RV that finds.
If selected client computer, herein for CSB, recognize server ip address SA, this client computer just can send this address to other client computer, described other client computer with the server ip address SA that transmitted in the client computer of distributing to other aspect it.Be distributed on subnet SNA, SNB and the SNC by this way server ip address SA tandem type.
In Fig. 5, exemplarily described, how server ip address SA is transmitted to the client computer CL of its oneself subnet SNB and crosses over subnet ground by its output module OUT from selected client computer CSB and send selected client computer CSA to, and the IP address of client computer CSA is known owing to aforesaid inquiry in client computer CSB.So client computer CSA sends server ip address SA client computer C1, C2 and the C3 of its own subnet SNA to and sends selected client computer CSC to with crossing over subnet, this client computer CSC finally continues server ip address SA to send to the client computer CL of its own subnet CNC.The transmission of server ip address SA can for example be finished by a so-called circular report.
All Clients CSA, CSB, CSC, C1, C2, C3 and the CL access on server S RV of essential network by this way, this server transmits the IP address SA that is used for access necessity.Therefore described client computer CSA ..., CL belongs to server S RV on the meaning of client-server-relation.
The present invention allows a client computer decentralized control and that oneself organize operation ground, ground will be distributed on a plurality of subnets on a large scale to distribute to its server.Therefore economize out the equipment of a kind of manual configuration or concentrated message business, such as DNS (domain name system) or DHCP.If but in network, there has been such concentrated message business as DNS or DHCP, should business can advantageously comprise in inventor's notion so in simple mode.So for example can equip selected client computer like this, this client computer also can be concentrated dns server and/or Dynamic Host Configuration Protocol server according to the IP address SA inquiry of the server S RV that is sought outside other selected client computer.Can equip like this according to a kind of enforcement variation DNS-of scheme or Dynamic Host Configuration Protocol server, this server is taken action on the meaning of the inventive method as selected client computer.By comprising the concentrated message business of existence, as DNS or DHCP, the distribution of the duration of searching server and the IP address of server can be continued to reduce.
Carry out the inventive method and require not revise server to be sought, and only revise the client computer that this method is supported.According to the client computer of this method support of embodiment that exists is in order to replenish the selection module CSEL of a client computer that is used to select own subnet.Preferably arrangement like this of client computer that this method is supported in addition, the information exchange of the selected client computer of this client computer support and own subnet, and this client's function is handed to the inquiry of the selected client computer of other subnets the selected client computer of own subnet.At a selectable client computer place according to the embodiment that exists must add one of installing seek module, herein for SM, be used to cross over subnet ground seek selected client computer and install a memory, herein be MEM, be used for storage server IP address SA.This external selectable client computer place also install an output module, herein for OUT, send the selected client computer of the inquiry outside own subnet and the client computer that sends the inquiry of own subnet to the server ip address SA that will be stored.
